Can someone help me solve this and explain step by step algebraically <br> 1/8x+1/4y=2
mote1985 [20]

Answer:

x=16-2y

Step-by-step explanation:

\mathrm{Subtract\:}\frac{1}{4}y\mathrm{\:from\:both\:sides}

\frac{1}{8}x+\frac{1}{4}y-\frac{1}{4}y=2-\frac{1}{4}y

\mathrm{Simplify}

\frac{1}{8}x=2-\frac{1}{4}y

\mathrm{Multiply\:both\:sides\:by\:}8

8\cdot \frac{1}{8}x=8\cdot \:2-8\cdot \frac{1}{4}y

\mathrm{Simplify}

x=16-2y

How do I do this problem
Lena [83]

First you multiply 3 times x and 3 times 2 

4(3(x + 2) -1) =50

and get

4( 3x +6 -1) =50

then you add 6 plus -1

4 ( 3x +5) = 50

then multiply 4 times 3x and 4 times 5

12x +20 = 50 and subtract 20 from both sides

       -20    -20

and you will get

12x = 30

divided both sides by 12

12x/12 = 30/12

then you find the ones that are the same amount in decimals but are smaller

and that's your answer: x= 5/2


hope you get it!!!
